Description

Disodium Isooctyl Phosphate is an organophosphate surfactant and anionic emulsifier. This compound is valued for its excellent wetting, dispersing, and emulsifying properties in demanding industrial formulations. It is primarily utilized in sectors requiring high-performance surface-active agents, such as agrochemicals, metalworking fluids, and textile processing.

Application

• Agrochemical Formulations: Acts as a key wetting agent, dispersant, and emulsifier in pesticides, herbicides, and fungicides.
• Metalworking Fluids: Serves as an effective emulsifier and corrosion inhibitor in synthetic and semi-synthetic coolants and lubricants.
• Textile Processing: Used as a scouring agent, wetting agent, and dye leveling assistant in fiber treatment and dyeing baths.
• Industrial Cleaners: Functions as a surfactant in heavy-duty alkaline and acid cleaners for industrial equipment and surfaces.
• Personal Care: Employed as a mild surfactant and emulsifier in select rinse-off cosmetic products, such as shampoos and body washes.
• Paint & Coatings: Aids in pigment dispersion and stabilization in water-based coating systems.
• Polymerization: Can be used as an emulsifier in the emulsion polymerization of specific monomers.
